3. Figure 2
Survival rates by rhythm and therapy type. Survival among patients treated only with ATP was identical to that in patients with no VT, whereas survival among patients who received shocks was significantly worse. The three patient groups were similar with respect to baseline predictors of mortality, which is consistent with the modeling results.

4. Figure 3
Progression of arrhythmia burden by appropriate shock groups. Patients are partitioned by number of appropriate shocked episodes over follow-up (horizontal axis) and corresponding annualized rate of VA by episode type and therapy applied (vertical axis). Left panel: Increasing annualized rates of all VA types with increasing shock burden. Right panel: Increasing annualized rates of all VA and therapy types with increasing shock burden.

5. Figure 4
Ventricular episodes and therapy types by survival status. VA episodes per patient month, segregated by type and therapy applied, are displayed among subjects who died compared with survivors. The monthly burden of all VA episode + therapy type combinations is higher among patients who died.
